With the development of oil recovery technology, ultrasonic technology has been involved in oil production and oilfield development. The mechanism of ultrasonic wave plugging in near well is different from the conventional oil recovery technology. Ultrasonic oil production technique is an effective method to enhance oil production with low cost, good applicability, and no environmental pollution. The core part of ultrasonic oil production equipment for Enhanced Oil Recovery is a high-power ultrasonic transducer. The continuous high-power ultrasound is used to treat the reservoir, which changes the pore structure, the physical property and the state of the fluid, thus improving the permeability and flows conditions of the reservoir, and increasing the oil yield and oil recovery. Ultrasonic oil recovery equipment includes the generation of high-power ultrasonic signals, long-distance transmission and the conversion of electrical energy to acoustic energy. In this paper, state-of-the-art on the development of ultrasonic oil production devices for Enhanced Oil Recovery in China is introduced. The purpose of this paper is to provide a reference for the development of high-power ultrasonic oil extraction equipment and its promotion in tertiary oil recovery technology.
随着采油技术的发展，超声波技术已经涉足采油和油田开发领域。超声波近井堵塞的机理不同于常规采油技术。超声采油技术是一种低成本、适用性好、无污染的有效采油方法。强化采油用超声波采油设备的核心部分是大功率超声波换能器。连续的高功率超声波用于处理储层，改变孔隙结构、物理性质和流体状态，从而改善储层的渗透率和流动条件，提高产油量和采收率。超声采油设备包括高功率超声波信号的产生、远距离传输以及电能到声能的转换。本文介绍了中国强化采油用超声采油设备的最新发展情况。本文的目的是为大功率超声采油设备的开发及其在三次采油技术中的推广提供参考。
